Australian researchers use HIV to prevent AIDS
Voice of America    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Australian scientists at the Queensland Institute of Medical Research say they have found a way to use the human immunodeficiency virus, or HIV, to prevent AIDS, describing the technique as "fighting fire with fire." Senior researcher David Harrich has designed a way to modify a protein in HIV to alter the virus so that it provides long-lasting, and possibly permanent, protection against AIDS, the disease that HIV causes.

New tick-borne infection similar to Lyme disease found in humans
New Haven Register via The Reporter    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A new tick-borne infection, similar to Lyme disease, has been found in humans in the Northeast region for the first time, according to researchers at the Yale schools of Public Health and Medicine. And while its unfamiliarity may result in some misdiagnosis — the disease, carried by deer ticks, has yet to be given a name — the good news is that the same treatment used for Lyme disease will cure this infection as well.

NY hospital patients potentially exposed to HIV, hepatitis through reused insulin pens
The Associated Press via CBS News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
More than 700 patients admitted to the Veterans Affairs Western New York Healthcare System in Buffalo, N.Y., over a two-year period may have been exposed to HIV, hepatitis B and hepatitis C, authorities said. Officials made the announcement following a review that found that multi-dose insulin pens intended for use by a single patient may have been used on more than one person. More

'Quadruple helix' DNA seen in human cells
BBC    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Cambridge University scientists say they have seen four-stranded DNA at work in human cells for the first time. The famous "molecule of life," which carries our genetic code, is more familiar to us as a double helix. But researchers tell the journal Nature Chemistry that the "quadruple helix" is also present in our cells, and in ways that might possibly relate to cancer. More

Handheld mobile device performs laboratory-quality HIV testing
American Association for Clinical Chemistry via ScienceDaily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
New research appearing in Clinical Chemistry, the journal of American Association for Clinical Chemistry, shows that a handheld mobile device can check patients' HIV status with just a finger prick, and synchronize the results in real time with electronic health records. This technology takes a step toward providing remote areas of the world with diagnostic services traditionally available only in centralized healthcare settings. More

Cell communication protein may be key to better cancer drugs
University of Georgia via Laboratory Equipment    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Even when at rest, the human body is a flurry of activity. Like a microscopic metropolis locked in a state of perpetual rush hour traffic, the trillions of cells that make us who we are work feverishly policing the streets, making repairs, building new structures and delivering important cargo throughout the bustling organic society. For everything to work properly there must be something to organize and direct the various workers. Enter protein kinases. More

Study: TB drug shortages put US patients in peril
HealthDay News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Shortages of key tuberculosis drugs are posing a real hazard to patients throughout the United States, a new report finds. The shortages are making it even more difficult to treat what's known as multidrug-resistant forms of the infectious respiratory illness, the researchers said. These patients often require so-called "second-line drugs" when the medication of choice fails. More

Biomaterial improves knee cartilage repair
Johns Hopkins University via Laboratory Equipment    Share    Share on FacebookTwitterShare on LinkedinE-mail article
In a small study, researchers reported increased healthy tissue growth after surgical repair of damaged cartilage if they put a hydrogel scaffolding into the wound to support and nourish the healing process. The squishy hydrogel material was implanted in 15 patients during standard microfracture surgery, in which tiny holes are punched in a bone near the injured cartilage. The holes stimulate patients' own specialized stem cells to emerge from bone marrow and grow new cartilage atop the bone. More
